The Perfect Tool - Life is Short So Just Buy It.
Size: 88mm x 15
So.
Life is too short to struggle with little demons and other inconveniences. I change oil in all my cars, trucks, and SUVs.
One of my cars is a V6 Hyundai and the filter cartridge is inside a housing that is sometimes more than a tad inconvenient to loosen and screw back in place. My regular filter removal tools including strap style as well as a three arm gripper type just did not perform very well.
I saw this thing, ordered it, and man...it is perfect. The metal top allows a wrench ( spanner) or a socket wrench to be used. I have a fancy Snapon torque wrench which I can also use just to be fancy. In any case removing and re-securing the filter housing on the Hyundai V6 is now a breeze. The cap wrench itself is solid and very well constructed
Five stars and count me in as impressed. Well done CTA Tools !!!

Good fit and easy filter removal
Size: 88.5mm x 16
Purchased this for my 2022 Volvo XC60 PHEV. Used up all my 'free' dealer oil changes and not ready to drop hundreds on a simple operation. Removal of the oil filter housing on this car would be nearly impossible without this tool due to its location. With it the process was simple. On a side note, the dealership 'pros' stripped every one of the plastic splash guard nuts. Obviously in a hurry with a power tool. They also did not change out the smaller o ring included with the filter. It's a pain to remove and mine was hardened and likely original. Anyway, placed this tool in drawer with the rest of my oil wrench collection.

Perfect fit on an AMSOIL Oil Filter EA15K51n
Size: 76mm x 14
This is a very well made oil filter wrench and while some are complaining about no exterior weld on the drive nut, if you look inside the weld is very plain to see and appears to be CNC welded so it's perfect and quite strong.
I like the finish of the wrench, it's easy to wipe off and if there is oil or debris anywhere on it, you'll be able to spot it immediately and wipe the part off to insure a nice, clean installation.
